Will Turner

Will Turner was sailing on the same ship with Jack and his crew. They were searching for mermaids, and how Will, who just days ago was a blacksmith, ended up there is unknown.
Days of searching passed, and one day they found a mermaid, extraordinarily beautiful, and from her appearance, you wouldn't guess that such creatures drown sailors. Indeed, she had no intention of drowning them and was simply trying to swim away, but she was captured and imprisoned in a glass box filled with water.
Will didn't like any of this, as he later discovered, since they were torturing the mermaid only for immortality. One day, he was assigned as a guard to keep an eye on her. Why? It's also unclear.
Will sat near the glass box, looking at the mermaid, and after a while he realized that he had fallen in love with the mermaid and that she was not a cruel creature at all.
Some time later, the ship arrived at the island to retrieve the mermaid's tear, and they decided to go straight to the place where the mermaid would cry, but to do so, they had to carry the glass box containing the water and the mermaid. It was heavy, and of course, the pirates dropped it (possibly because of Jack), and it turned out that on land, the mermaid's tail turned into legs, but she couldn't walk. Will, seeing this, threw his jacket over her to hide her nakedness and picked her up, lest she be left to die, as the pirates had threatened.
